KOHl/T' Fl6.4 F165 ATTORNEY Patented Aug. 21, 1951ATTACHING MEANS FOR CARBON PAPER PACKS OR THE LIKE Robert A. Kohut, NewYork, N. Y., assignor to Queen Ribbon and Carbon Co. 1110., Brooklyn, N.Y., a corporation of New York Application June 11, 1949, Serial No.98,505

This invention relates generally to means for temporarily attaching aflexible sheet or paper packs to a support and has particular referenceto means for attaching a carbon paper pack to the cross bar or blade offanfold billing machines or manifold-type machines, The said means arealso employable for attachment of sheets in con nection with typewriterswhere continuous forms are used.

A carbon paper pack for use with a fanfold billing machine ormanifold-type machine, comprises a plurality of sheets having their rearedges bound together by any suitable means, such as stitches, each ofthe sheets being folded back and forth to provide a number of layers ofsubstantially equal length. These folded sheets are positioned in andsecured by said stitches to a folder or binder which consists of a sheetof relatively heavy paper folded at its top providing a backing and afront flap for the plurality of carbon sheets. The folded top of thesaid sheet of relatively heavy sheet of paper is spaced from the top ofthe bound carbon sheets, thus providing a tubular slide for theaforementioned cross bar or blade.

It has been found that when the said cross bar or blade is inserted insaid tubular slide portion of the folder or folded binder, because ofthe usual loose fit, the cross bar or blade inconveniently slides ormoves relatively to the latter making complete adjustment or attachmentof the carbon paper pack thereon uncertain thereby interfering withefficient operation of the machine.

It is, therefore, an object of the present invention to provide a carbonpaper pack with means whereby the latter may be easily readily attachedand detached from the usual cross bar or blade of the aforementionedmachines.

It is another object of the present invention to 'provide a carbon paperpack or even a single sheet with means for temporarily afiixing the sameto a bar or other support.

A further object of the present invention is to provide a pack or asheet with perforations and a pressure sensitive adhesive strip over theperforations whereby means are provided extendable through theperforations by hand pressure on the strip for removably attaching thepack or sheet to a flat member.

A still further object of the present invention is to provide theaforementioned fiat member with the perforations and with the pressuresensitive adhesive strip for the purpose of removably attaching a packor sheet to the flat member.

2 Claims. (Cl. 282-19) According to one phase of the invention, a carbonpaper pack is provided with a jacket, folder or binder having a fold atthe top of the pack constituting a fiat tube or loop within which a baror blade may be slipped; the said fold being provided with perforationsover which an ad hesive strip is secured. By applying a slight pressureto the said strip portions, the latter will enter the perforations andthe adhesive coating on the said strip portion will adhere to the saidblade or bar holding it in fixed position and against lateral movementwithin the said tube or loop portion of the binder.

Various further and more specific objects, features and advantages willclearly appear from the detailed description given below taken inconnection with the accompanying drawing which forms a part of thisspecification and illustrates merely by way of example two embodimentsof the device of the invention.

The invention consists in such novel features, arrangements andcombinations of parts as may be shown and described in connection withthe articles herein disclosed by way of example only and as illustrativeof certain preferred embodiments.

In the drawings, Fig. 1 is a plan view of a carbon paper pack embodyingthe invention;

Fig. 2 is an end view thereof;

Fig. 3 is a sectional view taken through line 33 of Fig. 1;

Fig. 4 is a plan view of a sheet of material in-- corporating theinvention;

Fig. 5 is a sectional view taken through line 5-5 of Fig. 4;

Fig. 6 is afragmentary view showing an application of the invention in amodified form; and

Fig. 7 is a sectional view taken through line of Fig. 6.

In the following description and in the claims, parts will be identifiedby specific names for convenience, but such names are intended to be asgeneric in their application to similar parts as the art will permit.Like reference characters denote like parts in the several figures ofthe drawing.

Referring now to the drawing, there is disclosed a carbon paper pack l0comprising a plurality of folded sheets of carbon paper I2. Folded overthe top of said plurality of sheets i 2 is 3, flexible sheet I I of anysuitable material, the fold line I ha of the folded sheet ll beingspaced from the top l2a of the said plurality of carbon sheets I2providing a flat tube or longitudinal passage H! for the reception of aconventional cross-bar or blade 15 usually employed for use with amanifold-type machine or the like. The said blade or bar 15 is providedwith the usual slot l5a for connection with the said machine. Spacedrows of stitches l3 and i6 secure the plurality of carbon sheets 12 andfolded sheet ll together. The folded sheet H is perforated as indicatedat H. These perforations may be provided on either one or both sides ofthe folded sheet. Adheringly disposed over the perforations I? is anadhesive strip l8 of preferably pressure-sensitive or tacky material. Itis apparent that if the blade or cross-bar I5 is inserted in the passage14 and a slight finger-pressure is then applied to the adhesive strip 18over the perforations ll, the tacky portions of the strip 18 will occupyspace within the perforations and its adhesive surface will adhere tothe bar 15, thus fixing the bar and preventing shifting thereof.

Figs. 4 and 5 illustrate the invention as applied to a single sheet 25having the perforations 26 and the adhesive strip I 8 fixed over theperforations.

Figs. 6 and '7 disclose the invention in a modified form, in that thebar 3| is provided with the perforations 32 and the adhesive strip 18 isfixed to the blade or member 3| over the perforation 32.

It is apparent that the sheet 30 may be adhesively secured to the memberSi in a. manner heretofore stated as regards the previous figures.

Having thus described the invention, what is claimed as new and desiredto be secured by letters patent, is:

1. A carbon paper pack comprising a plurality of sheets, a flexiblesheet folded over the top of said plurality of sheets with its fold linespaced from said top whereby a longitudinal passage is formed, meanssecuring together said plurality of sheets and said flexible sheet alonga line spaced from said fold line, at least one perforation in thefolded over portion of said flexible sheet communicating with saidpassage, a strip of flexible material having a, pressure sensitive tacksurface adhering to said folded-over portion of said flexible sheet andcovering said perforation, said passage being adapted to receive alongitudinal member and a tacky surface of said strip being adapted toadhere to said member through said perforation when said member isinserted in said passage to underlie said perforation.

2. A carbon paper pack according to claim 1 wherein there is at leastone perforation on either side of said folded-over portion and a stripof flexible material having a pressure sensitive tacky surface adheringto each side of said folded-over portion over each perforation.
